Overhead cranes move towards full automation

Growing awareness of the benefits of full crane automation is currently the most noticeable trend in Africa’s overhead crane industry.

This is according to Marc Kleiner, managing director of leading local crane manufacturer Condra, where records show a significant increase in the number of tender documents specifying provision for crane automation post-installation.

He was commenting on market characteristics emerging during the year just ended.

Kleiner said that although Condra received no orders for fully automated cranes during 2022, the number of enquiries for such machines was well up year-on-year. “Repetitive crane operations such as those in refinery operations offer clear potential for increased productivity through automation,” said Kleiner. “South Africa has the technology and local manufacturing capability to deliver it, and now the market is becoming increasingly aware. I don’t think we will have to wait long before automation gains a foothold.”

Full automation implies zero involvement by machine operators. It is the ultimate step beyond an overhead crane in which the machine executes a limited number of pre-programmed, automated operations, but still needs an operator to control the crane during randomised, non-repetitive lifting functions (semiautomation).

Kleiner stressed that Condra has offered full automation across its product range since 2020, the culmination of continuous development since the company’s first semiautomated crane installation at a Durban spice company in 2003. That machine comprised a grabbing crane installed to pick spices and transport them to specific points for release over hoppers servicing blending and packing operations.

Pointing to the motor industry for indicators of anticipated advances in overhead crane technology, Kleiner said that motor vehicles often led technological development in crane manufacture by several years, but that in the case of automation, these roles had been reversed, with overhead cranes currently leading the way forward.

“Vehicle manufacturers were first to use computers to monitor certain mechanical functions,” Kleiner explained.

“Crane manufacturers lagged this development, and it was a similar case with the control and smoothing out of lifting and lateral movement. It took time for crane manufacturers to introduce variable speed drives, whereas comparable control technologies had been present in motor vehicles for decades.

“This is not the case with automation, however. With automation, the crane companies are in the lead,” Kleiner said. “The autonomous crane exists and is already performing useful work, whereas the autonomous motor car is still in the experimental phase.”

Kleiner noted that about one in five enquiries received by Condra now includes specified provision for future automation, a requirement met by incorporating wheels and rails with tighter tolerances, and provision of fitment and wiring points for the future attachment of cameras with cognitive movement control ability, the main requirements for automation.

Asked about other trends in the overhead crane industry emerging during 2022, Kleiner pointed to the fragmentation of the market into two main types of supplier: those delivering specification-driven overhead cranes of the highest possible quality designed and manufactured to fulfil a specific customer function, and other companies importing lower quality machines for shoehorning into the application.

“There are still companies out there hoping to make a quick fortune,” said Kleiner. “They don’t manufacture locally, so they buy the closest suitable standard machine abroad with an eye getting the job done in the short term. They are not looking to the long term, and these types of cranes generally fail early on under the stress of the application.”

Kleiner noted that this trend has been exacerbated by the formation of small, splinter companies resulting from the downsizing of some of South Africa’s key

multinational crane manufacturers. “Retrenched staff frequently form small start-ups allied to an external manufacturer in Europe or China. They supply a standard machine, the engineering of which often fails because the design is not suitable, forcing the supplier to redesign and rectify after commissioning with a consequent halt to the customer’s production,” he said.

Kleiner concluded the interview on an optimistic note:

“Condra is in a good position going into 2023. We have a solid order book which includes contracts recently signed with steel companies and mines across Africa both above and below ground. Locally, our factories in Cape Town and Johannesburg are busy.

“The market is aware that Condra represents more than just crane manufacture and commissioning, offering design and engineering skills that dovetail with those of architects and structural engineers. We have considerable experience of working with these disciplines to deliver world-class, best possible lifting solutions within tight lead times.

“This is a strong foundation on which to build a successful 2023,” Kleiner said.

CM Labs upgrades Forklift Simulator Training Pack for Ports and Construction

Blended training solution offers increased trainee engagement with heightened visuals and improvements to learning program.

MCM Labs Simulations, global simulation training provider in the construction and ports industries, has announced the updated release of its Forklift Simulator Training Pack.

The Forklift Training Pack is the only simulation-based solution that exposes trainees to real forklift hazards and challenges. It offers a safe, effective, and comprehensive alternative to initial training. The simulation training mitigates

increased fuel costs and wear and tear that typically result from inexperienced handling while addressing key industry issues such as labour shortages, safety, and sustainability.

Upgrades include improved graphics for better immersion, new virtual environments, and reworked exercises. The Forklift Training Pack’s progressive learning exercises gradually build skill and confidence. Trainees work on skills such as

control familiarization, transporting, loading and unloading materials of varying sizes and weights, managing ramps, manoeuvring tight turns, and braking. An exercise to prepare for certification and a “sandbox” for continued practice is included.

“The shortage of experienced operators highlights the importance of closing the skills gap,” said Alan Limoges, Construction Product Manager at CM Labs.

“That’s why we are focused on providing the most immersive learning experience to deliver the world’s best training outcomes.”

The Forklift Training Pack is compatible with all of CM Labs’ Vortex® Simulators, including the desktop Vortex Edge Plus, the motion-enabled Vortex Edge Max, and the high-immersion Vortex Advantage. The Forklift is part of CM Labs’ range of lifting machines, making it ideal for training schools or companies with a wide range of equipment in their fleet.

From one job to the next with the Palfinger FLC 253 truck mounted forklift

It’s powerful, manoeuvrable, and versatile — the PALFINGER truck mounted forklift FLC 253. It demonstrates everything it can do when deployed to job sites in Sweden. No construction site is too small, too narrow or too challenging. Quickly unloaded from the truck, it completes its tasks in record time.

A typical construction site, bumpy terrain and enormous time pressure — a situation many transport companies know only too well, including the CEO of the Swedish transport company MIJ Transport, Zelimir Mijatovic.

Speed, manoeuvrability and maximum flexibility are the order of the day, and the PALFINGER FLC 253 truck mounted forklift delivers in full. When the transport company owner arrives at the next job site with his truck, he has the FLC 253 on board ready for action.

It means you have complete independence when delivering goods. With the TMF FLC 253, you don’t need assistance from third parties to unload on site.

Ready for action in record time

From construction to timber and recycling, the FLC 253 is used almost everywhere. With a load capacity of 2.5 tons, the truckmounted forklift can easily load and

unload heavy goods and building materials. Thanks to the ground control panel at the rear, it only takes 30 seconds for the forklift to undock from the Swedish transport company's truck and be ready for action.

The scissor lift makes it possible to load and unload materials from any side of the loading area so the pallets with construction material are unloaded from the truck one by one, carefully and safely, but also at record speed.

For example, working with the TMF FLC 253 is much faster than unloading materials using a tail lift. With the truck-mounted forklift onboard, MIJ Transport can deliver materials and goods to its customers faster and more efficiently and, as a result, complete more daily orders.

Customer service that’s special Zelimir Mijatovic appreciates the advantages of the FLC 253 and

can rely on PALFINGER quality for carrying out his work: “We often deliver goods and materials to our customers in difficult terrains, such as on large construction sites, where pallet trucks and conventional tail lifts have limited capabilities and are difficult to deploy. That is why we chose the PALFINGER FLC 253, which delivers impressive power and enormous manoeuvrability. This makes work much easier for us,” says Mijatovic. “Customers are often excited to watch the unloading process because it runs so smoothly. And that’s something special,” adds Mijatovic with a smile.

Powerful, flexible and always ready for action, the PALFINGER FLC 253 truck mounted forklift lives up to its reputation.

2 Trends driving demand for vertical mast lifts

Similar to what’s happening in the compact scissor lift and low-level access lift markets, demand today for vertical mast lifts is being driven by users’ need for machines that meet these core requirements.

• Smaller footprints to fit into smaller spaces

• Lighter weight to be used on different types of sensitive surfaces, like finished flooring

• Small (or zero) turning radius for enhanced manoeuvrability

• Ability to fit into freight elevators

Two trends increasing the demand for machines that match these requirements are:

1. The need to access narrower,

more confined work areas

2. The ability to work in weightrestricted applications

Let’s take a closer look at these trends and how JLG is responding. The need to access narrower, more confined areas

One of the biggest benefits of vertical mast lifts like the JLG® E18MML is that these machines allow users to access tight, confined indoor spaces like doorways,

stairways, hallways and other areas obstructed by infrastructure like in between tight racking, ducts for heating/cool work, pipes for plumbing and/or ceiling tiles and joists.

And because many models, like the JLG E18MCL machine, are rated for indoor and outdoor use, these models are well-suited for work in restricted outside areas like alleyways, on sidewalks and/or close to exterior walls of buildings. These types of machines are purpose-built to provide workers with access to high-reaching or overhead tasks in hard-to-reach places where ladders or scaffolding have traditionally been used.

Measuring between 2-3 ft wide, vertical mast lifts are the most compact type of aerial lift available to fit into small spaces. Additionally, vertical mast lifts boast up-andover capabilities, which means they can easily manoeuvre around fixed

obstacles at height.

The ability to work in weightrestricted applications

Many construction and facility maintenance jobs need to be done in areas that are difficult to navigate with larger, heavier machines, including traditional slab scissor lifts. In fact, that’s the biggest difference between vertical mast lifts and slab scissor lifts — the size. Not only do vertical mast lifts like JLG’s models boast a smaller footprint (a little more than 60 cm in width and length and less than 2m in height) and zeroturn capabilities for excellent manoeuvrability around job sites and facilities, but these machines are also lighter weight— many models weigh under 900kg.

Thanks to their lightweight design, JLG’s machines can be driven through a facility and used on finished or weight-restricted flooring such as carpet, concrete, ceramic or porcelain tile, hardwood, laminate, stone and vinyl.

And, being small enough to fit into

tight spaces and lightweight enough for use on sensitive flooring also means that JLG’s models can fit into and be moved between floors in standard elevators.

Another benefit of these machines weighing less and being so compact is that once the work is done, they can (when stowed) fit into small spaces like utility closets for storage when not in use.

A look at jlg vertical mast lifts

To meet market demand for these types of small, lightweight aerial lifts, JLG has two new vertical mast models available in the market: The E18MML and the E18MCL.

Both are tried and true, fieldproven products that offer an efficient and productive way to tackle up-and-over work and are an alternative to ladders and scaffolding.

These models feature a choice of castor-type steering that is ideal for use in maintenance, stock picking and warehouse applications (E18MML model), or scissor-type steering for construction use

(E18MCL model).

Thanks to the batteries being mounted under the platform, these JLG machines also are designed with improved machine weight distribution for efficient loading and unloading.

And, there are five different platform options to choose from to increase productivity.

Every JLG E18 platform option is equipped with exclusive “Quick Change” mountings for one-minute change-outs.

Both JLG models are engineered with a modern DC electric drive system, which comes available with long-running batteries for lasting performance.

Also, both models are available with a Stock Picker Package Option for stock and ordering picking applications in warehouses and distribution centres.

Genie® 13 ft / 4 m platform for boom lifts now available for use with three XC™ boom lifts

The Genie® 13 ft / 4 m platform for boom lifts is now available for use on three Genie XC™ (Xtra Capacity™) boom lifts in North America and the EMEAI region (Europe, Middle East, Africa and India).

The platform adds more than 60% additional room in the platform, increasing the versatility of rental companies’ boom lift fleets while boosting jobsite efficiency.

"This new platform offers benefits for equipment owners and operators. Because the expanded work space allows operators to cover more area, the number of boom movements required to get a job done can be cut in half, significantly boosting jobsite productivity,” says Logan Wood, Genie Associate Product Manager.“ At the same time, because the platform is compatible

with multiple Genie boom lift models and can be swapped for the machine’s standard platform the same day, it also offers rental companies a simple, cost-effective way to boost the versatility of the booms in their fleet.”

The 13 ft / 4 m platform will be on display in the Genie booth (#4247) at The ARA Show in Orlando, Fla., in February. Compatible with Genie S®-45 XC™, S-65 XC and S-85 XC boom lifts, the 13 ft / 4 m platform is especially well suited for tasks that involve an extensive working area, such as renovation and painting of buildings and

window cleaning and cladding, as well as jobsites with limited space to maneuver on the ground. In addition to increasing operator comfort, the extra space in the platform also allows workers to do more, faster, by providing access to twice as much work area with the same number of boom movements compared with a standard sized 8 ft (2.44 m) platform.

After following instructions to install the 13 ft / 4 m platform and calibrating the machine, the S-45 XC, S-65 XC and S-85 XC can take up to two workers to height and deliver a 600 lb (272 kg) lift capacity. Additionally, operators benefit from other features of Genie’s XC machines, including automatic envelope control, a smooth working curve and active load sense.

An off-center transport lock allows the machine to be transported on a standard trailer in most countries, keeping transport costs comparable to a boom lift with a standard-sized platform.

Overview of the 2023 budget speech

The minister of finance, Enoch Godongwana, presented his budget speech before parliament. Cornerstone would like to provide you with a summary of the main points without getting bogged down in the political jargon.

improve their systems and increase their revenue-raising capabilities. As a result, we expect SARS will not become any easier to deal with going forward, as they are under ever more pressure to collect more taxes and reduce unnecessary refunds.

Cornerstone has listened attentively to the Minister of Finance’s budget speech for the upcoming 2023–2024 tax year. We believe there are a few key takeaways that all businesses and individuals should keep in mind during the coming year.

Renewable Energy Incentive

The highlight of the speech was the announcement that there would be a tax incentive for renewable energy spending to ease the stress on households and businesses caused by load shedding. The most significant incentive is for businesses, which can deduct 125% of all renewable energy investments for two years beginning March 2023. This means that if your business spends, SARS will allow your business to reduce the income it gets taxed on by R125 for every R100 that was actually spent. This incentive is interesting because there is neither a minimum nor a maximum. This incentive is interesting because there is neither a minimum nor a maximum. In essence, if your company (not an SBC) pays R1 million to install solar power, you would save R337,500 in corporate income tax. This expansion in Section 12B is exciting as it allows companies to install renewable energy without being impacted by load shedding. The more modest incentive for

individuals only applies to rooftop solar panels and is valid for one year beginning March 2023, with a rebate of 25% of the cost of the panels, up to a maximum of R15,000. While this sounds disappointing, it is not quite as bad as it might first appear.

The Minister specifically called this a “rebate,” and rebates reduce the amount of tax you need to pay, not the amount of income SARS taxes you on. In other words, the incentive applies after your income is multiplied by your tax bracket percentage. For example, if you are in the 36% tax bracket, an R15,000 rebate would cover R41,667 worth of your income, thus putting more money back into your pocket and making solar power more accessible.

SARS

It was said that SARS did better than expected and brought in R93,7 billion more in taxes than planned over the past year. In practice, we have seen the effect of this as SARS is becoming more stringent and heavy-handed with audits, rejecting disputes, and demanding payments. We have also seen a rise in the number of taxpayers who are caught avoiding or not paying taxes. There is also a proposal to increase SARS funding, specifically to

Tax rates

The only other notable news from the budget speech that should be relevant to almost everyone is that there are no changes to the business income tax or VAT rates. Also, individuals tax brackets, tax rebates, and medical aid credits will only go up by the amount of inflation.

There are a few interesting points that are worth mentioning

• Government is considering revisions to the ‘two-pot’ retirement system to be effective 1 March 2024

• The sugar tax will remain unchanged for two years going forward

• Alcohol and tobacco tax will increase by 4.9% from 1 March

• Public sector wages will increase depending on the ongoing negotiations with unions

In the end, the budget speech was much shorter than expected, and a lot of attention was paid to SARS’s ability to collect taxes in order to pay for government projects and rising debt costs.

Shumani has biggest fleet of Kalmar port equipment in South Africa

Shumani Industrial Equipment is the official distributor of Kalmar reach stackers and empty-container handlers in South Africa. “We currently hold the biggest fleet of Kalmar port equipment in South Africa,” highlights MD Victor Nemukula.

The Kalmar Essential reach stacker gives more value for money without compromising on quality. Built on the proven G-Generation platform, these machines are reliable, robust, highly efficient and are available with either EU3/Tier 3, EU4/ Tier 4F or EU5 or Korea Stage V emissions standards compliant engines.

Kalmar equipment is available for outright purchase or short term rental at affordable rates. “Most companies that require this

equipment either do not have the capital outlay to purchase outright, or do not want to put it on their balance sheet,” explains Nemukula.

To cater for these clients, Shumani has financial muscle to offer longer term rental if needed. As the largest owner of Kalmar equipment in its short-term rental fleet, Shumani can rent out these units on a flexible basis for up to 24 months.

“We are the only 51% black-owned, Level 1 BBB-EE in the country that

can offer forklifts and warehouse equipment, construction equipment and cleaning equipment on both outright purchase, long- and short-term rental in South Africa,” comments Nemukula.

Over the past eight years, Shumani has built up its in-house technical capabilities to provide services around the country. It strives to offer its customers 24/7 service and a two-hour response time in major metropolitan areas for all its equipment.

Looking ahead, the port and warehousing market continue to lead the way in terms of growth. “We are already seeing robust growth going into 2023 in these two market sectors,” reveals Nemukula. “New products will be announced this year once the necessary logistics have been finalised,” he concludes.

REST IN PEACE KEN GREENWOOD

It is with a heavy heart that we share the passing of Mr Ken Greenwood – an industry steward. Everyone who knew Mr Greenwood, knows how passionate he was about the industry and the safety thereof. Actively being a part of writing/amending standards and a mentor to majority of the LMI’s in our country. Nothing stood in his way when it came to offering training or presenting at conferences educating the industry, not even his health.

Ken, thank you for the opportunity you gave me 8 years ago to start Lifting Africa. I appreciate and will always cherish the endless hours you spent with me, educating me about the lifting equipment industry It is because of your guidance that we are able to be the voice we are today You were always just a phone call away, ready to share your knowledge with myself, my team and the industry Thank you for the love and kindness you have shown towards the Lifting Africa team – with every phone call you would ask how my team is doing, and they too are grateful for the impact you had on their learning path.

Our deepest condolences go out to his wife Esther Greenwood, his daughters Lynette & Stephanie, sons-in-law, family & friends. Our prayers & thoughts are with you.

Rest in peace Ken, your loss will be deeply felt.

Wall travelling cranes for the automotive industry

No two cranes are alike. But if you're looking for a very special solution, you need an engineering expert in this field, like Haslinger GmbH.

This crane manufacturing partner of STAHL

CraneSystems has implemented no fewer than four wall travelling cranes for a leading German car manufacturer at a site in southern Germany. Apart from the fact that such systems are rather rare per say, the cranes stand out for several special features.

Double-girder wall travelling cranes replace existing systems

The technical presentation and corresponding concept for implementing the planned project outlined in the course of a tender ultimately convinced the customer, resulting in Haslinger winning the contract in mid-2020. Specifically, the project involved the design, production, delivery, and installation of a total of four double-girder wall travelling cranes. In a first step, two systems were initially planned for a hall in which large tools to produce car body components are inspected and prepared. This hall already contained older wall travelling cranes, each with a lifting capacity of 5 t, but they were no longer able to cope with future logistical requirements and were therefore to be replaced by new cranes, each capable of lifting 8 t.

More flexibility and performance on a large area

Looking back, Robert Seibold, head of crane technology at Haslinger sees the construction of the wall travelling cranes as the real challenge in the project: “Compared to overhead travelling or suspension cranes, such cranes are rarely required. Moreover, these were very individual solutions according to customer specifications, for which we had to consider a whole range of requirements. In addition, the cranes had to be installed without disrupting work in the hall. This, however, we are familiar with from other projects and are able to adjust to in our planning and implementation."

The four wall travelling cranes serve as a supplement to an existing bridge crane and thus create a further plane of movement for multi-layered work processes. With a jib length of 8.4 m each and a crane runway length of 80 m, the new cranes can reach almost every point in the approximately 1,600 square meter hall. The wall travelling cranes are therefore able to serve all work areas simultaneously without having to use the main crane, which may not be immediately available because it is needed in another part of the hall.

More precision in lifting and lowering

The project was basically divided into two construction phases, with two wall travelling cranes being installed on one side of the hall in each phase.

"We had already prepared and reinforced the crane runways appropriately beforehand so that they could carry the loads of the new cranes. In order not to interfere with ongoing operations in the hall, the first two cranes were then installed over the turn of the year 2020/2021," Robert Seibold reports.

Haslinger chose a SH 5025-20 electric wire rope hoist with a reduced S.W.L. of 8 t and a lifting height of 6 m from STAHL CraneSystems' standard range as the hoist for one of the two double-girder wall travelling cranes. The SH series wire rope hoists come in five sizes with 27 S.W.L. variants from 500 kg to 32,000 kg. The compact, low-maintenance solutions can be used for stationary lifting operations or with a trolley (in this case an overhead trolley with a maximum travel speed of 10 m/min) in standard and off-standard cranes. In this connection, although all hoists used in this project are standard wire rope hoists, they were customized according to the customer's wishes and equipped with additional safety technology, among other things.

Robert Seibold gives an example: “The wire rope hoists normally achieve a maximum lifting speed of 10 m/min. However, the customer wanted the speed to be halved, which we solved with an intermediate gear. A lifting speed of now 5 m/min enables even higher precision when lifting and lowering loads."

Continuous recording of important operating data

One essential component of the SH 5025-20 wire rope hoist for this project is the STAHL SMC 22 multicontroller for continuous load measurements with automatic load control, which immediately switches off the hoist in the event of an overload. As load spectrum memory, the SMC also records a wide range of operating data in real time, including the operating hours, the full-load operating hours, the number of motor switching operations and many other parameters that are important for equally reliable and safe operation of the hoist. Using STAHL CraneSystems' free ConfigTool, the operating data can be read out and evaluated quickly and easily by the operator on a PC or laptop.

"The prescribed annual calculations of the service life of a hoist can also be carried out very accurately with the SMC. In addition, if there should ever be an incident with a crane, the recorded data may make it possible to trace the causes," says Robert Seibold, describing just a few of the advantages of the system.

Single and tandem operation with integrated load aggregation

The second wall travelling crane is identical in design

to the first but is distinguished by a number of further special features for which, among other things, the crane's statics had to be designed. Two hoists travel on the upper flange of this crane, more precisely two SH 6040-10 electric wire rope hoists from STAHL CraneSystems with double-grooved rope drum and 4/2 reeving, which prevents lateral hook movement when lifting and lowering loads.

The hoists, also designed for an S.W.L. of 8 t each and a lifting height of 6 m, permit either single or tandem operation and thus offer a high degree of flexibility in use. Load aggregation with a safety PLC is also integrated for tandem operation. It permanently measures and monitors the loads on both crane hooks, thus ensuring that the permissible total load capacity of the crane of 8 t is not exceeded. "In tandem operation, it is possible to transport longer tools more easily and position them more precisely. At the same time, the load is kept in a stable position on both hooks, which, among other things, also prevents the swinging of the load. In a single operation, the tools can, in turn, be turned and rotated safely," explains Robert Seibold and underlines: "In my view, load aggregation with a safety PLC is a certain unique selling point for STAHL CraneSystems' wire rope hoists because the solutions have a very high safety level as a result. The control systems are designed in accordance with EN 15011 and fulfil the high-performance level PL c or PL d depending on requirements."

Special design for the travel axis

Haslinger also realized a special design for the cranes' travel axis using STAHL CraneSystems’ standard end carriages and wheel blocks consisting of three crane runways on each side of the hall. Each crane has two frequency-controlled travel drives on the lower end carriage, which runs on the middle crane runway. With four wheel blocks each, the very high pressure forces are distributed evenly on the lower crane runway. Last, but not least, a so-called crane distance control was installed on all cranes. The solution in the form of a photo-electric barrier with optical sensors prevents accidental collision of two cranes in operation on one travel axis by automatically reducing the speed of the

moving crane when it approaches the neighbouring crane.

Successful completion of the second construction phase

Due to the far-sighted planning and organization in advance, the de-installation of the existing cranes and the complete installation of the first two new wall travelling cranes, including commissioning, took only two weeks.

The car manufacturer was obviously extremely satisfied with the results of the project because in March 2021 Haslinger received the order for the two additional wall travelling cranes, which are identical to the first solutions. They were put into operation in the summer of 2021 during a planned break in the car manufacturer's production.

"We have become experts in the engineering of offstandard crane systems in recent years. The successful project at the car manufacturer is an example of our individual complete solutions, optimally tailored to the customer's needs thanks to STAHL CraneSystems' modular system," is Robert Seibold's positive conclusion.

Different types of cranes used in ports

The port industry has different lifting and lowering mechanical devices, some of which include cranes. These machines are capable of lifting different weights for and from various heights and from any boat or ship. To work effectively, hoists use cables and pulleys.

What are the different types of port cranes?

There are different types of port cranes, depending on the work to be handled. The port is usually a beehive of activities; therefore, it requires the right mechanical tools to ensure maximum efficiency. Port cranes are specially designed to load and offload bulky goods like containers that weigh tons. This is the list of the best port cranes and their uses and specifications are explained below.

Panamax Cranes

The term Panamax is derived from the name given to ships passing through the Panama canal. These

automatic dock cranes extend up to 30 m and reach a lifting height of 36-38m. Panamax cranes have up to 13 containers on the cover. In a single lift, these cranes can be loaded with approximately 40-50 tons while in a double lift, it lifts to 65 tons.

In terms of speed, they have a lifting speed of 50-125 meters per minute, the movement speed of 45 meters per minute, and a carriage travel speed of 150-180 meters per minute. Their wheel load ranges from 30-40 tons per meter. Panamax cranes are used to load and unload containers from ships to the port or vice versa.

Post Panamax

These are modern port cranes more giant than the Panamax cranes. They hold up to 16 containers on the cover. They reach up to 45 meters with a lifting height of 35 meters. Like the Panamax crane, their workload ranges from 40-50 tons in a single raise and 65 tons in a double lift.

The lifting speed is 60-150 meters

per minute, while the carriage speed is 180-210 meters per minute.

The crane moves at 45 meters per minute, with a wheel load of 40-55 tons per minute, which is more substantial than most port cranes. They are used to load and offload containers from ships too large to pass through the Panama Canal.

Super Post Panamax

They are the enormous docks crane at the moment. Many ports around the globe are now getting this crane for better and faster operations at the port. Their spreader can accommodate approximately 65 tonnes when it’s a double lift. A tandem lift carries a workload of 110 tonnes and can scope up to 53 m and have a lifting height of 40 meters.

Additionally, these type of crane lifting container are characterized by a lifting speed of 70-175 meters per minute, movement speed at 45 meters per minute, and a carriage speed of 210-240 meters per minute. These cranes weigh about

4. Floating cranes

5. Bulk handling cranes

6. Gantry cranes

7. Hammerhead cranes

Tower cranes

Deck cranes

Rough terrain cranes

Overhead cranes

180-190 tons, with a wheel load capacity of 70-80 tons per minute.

Floating Cranes

These are vessels that consist of winches attached to them. They are mostly used in the construction of harbours and bridges. These devices are also used in loading and unloading of unusually heavy objects in the port. Vessel hoists have the ability to lift over ten thousand tonnes.

The floating type can also be used to recover sunken ships by use of the crane hook. Another important feature is that these vessels can move from one place to another. This means that they are flexible enough to move objects to designated locations. Some common types include semi-submersible and sheer legs.

Bulk-Handling Cranes

In ports, the most efficient and reliable method of handling the numerous amounts of bulky goods is by the use of grabbing hoists, which are operated through riggings. Bulk-handling winches are very efficient when it comes to controlling such materials as gravel, coal and foodstuffs like grain.

Basically, they are useful in loads that prove difficult for man and other machines to handle. These devices are available as mobile or fixed devices. Bulk-handling machines can help a crane operator to handle about 2,300 tonnes every hour.

Gantry Cranes

Gantry cranes can be used in different industries. These machines are available in fixed or adjustable heights and are either made of steel or aluminium, depending on their purpose. The basic design of these machines features two upright beams that are attached to each other by a horizontal one. These two upright beams are linked to two A-shaped frames, which have wheels attached to them. This feature makes them movable and portable. The smaller version of gantry cranes is mostly used to move larger objects in the construction industry and in docks to move containers. In other instances, larger versions of this lifting device are used in such working areas as warehouses.

Hammerhead Cranes

This is one of the most common types of cranes used in ports and it’s also known as a giant cantilever. Hammerhead winch consists of a tall steel tower, which holds a horizontal double cantilever fitted with a lifting trolley that has a crane hook. The jib extends backwards, an important aspect for weight balancing. Note that the hammerhead wrench system is made with a racking motion that allows back and forth movements of the trolley. This motion also prevents interference with the height of the load. These cranes are also created in huge sizes and can lift loads of over 350 tones.

Tower Cranes

This is a modern type of balance wrench that is

usually fixed on the ground. Tower cranes give a good combination of lifting capacity and height. They are mostly used to lift loads to very high heights, especially in shipyard constructions and to lift containers in havens. Extremely tall cranes can reach up to 1,000 metres high with a base of about 3.5 metres.

Deck Cranes

A deck crane can be found on a ship or boat. They are mostly used for cargo operations such as loading and unloading. These machines are also very useful for goods retrieval on shores that do not have unloading devices. Most of them are hydraulically operated. This means that they either use electric or diesel-hydraulic system.

Rough Terrain Cranes

Normally, this is mounted on a carriage that is fitted with four wheels and is designed for places with a rough terrain. When hoisting, the outriggers extend both horizontally and vertically to balance and keep it stable. These rough terrain hoists use a single engine to power both its winch and undercarriage. The ability of this machine to manoeuvre through rocky and gravel filled places makes it very effective for carrying heavy loads through construction sites.

Overhead Cranes

An overhead crane is also called a suspended crane. Although they are mostly used in factories to lift heavy loads, a goliath crane is also used in a shipyard. They consist of hoists that are set on trolleys. The trolley is fitted in a way that allows it to travel along one or two beams. It also moves at angles in the same direction along the ground and elevated level.

Overall, these mechanical devices are very interesting and powerful machines. A crane operator is highly trained to control and maintain these devices. Due to their ability to lift heavy and bulky loads for great heights, the gadgets are very useful for construction and port operations.

Elebia Hooks, the right solution for ports

The elebia hook is a compelling hook that is a must-have for port operators. It comes with excellent features that assure you of great hook performance. For a coherent working of any system, the system must be complete, and all parts

have to work efficiently. Therefore, automatic crane systems need to have a robust and reliable Evo crane hook.

The elebia automated hook suite all types of automatic cranes such as the Panamax and post-Panamax. These great hooks have a swivel with bearings. The swivel ensures that the hook moves freely. As the operator, the swivel will enable you to fix a hook on an immobile position.

The automatic elebia hooks come with an electric motor protected with a clutch to avoid overloading. Another fantastic feature is its structured steel body with high strength and corrosion-resistant polyester coating to withstand harsh working conditions.

As an operator, you can adjust the release limit with the precise electronic torque and ultimately eliminating massive rigging problems and having your logistic operations streamlined and productive.

New 300|AT Reimagines all-terrain platform at Link-Belt

Link-Belt Cranes has announced its all-new 300-ton (250-mt) 300|AT allterrain crane will debut at CONEXPO-CON/AGG ‘23 in Las Vegas, Nevada (March 14 – 18, 2023). Following valuable voice of the customer data collection as well as engineering and manufacturing research, Link-Belt Cranes is debuting an entirely new crane platform with the 300|AT.

“We spoke extensively with our customer base and feel like we have delivered. They want a crane that travels down the road efficiently, goes together on a jobsite quickly, has a strong chart, and is reliable,” said Andrew Soper, Product Manager Telescopic Truck and AllTerrain Cranes.

The 300|AT is a five axle all-terrain crane built with transportability in mind meeting all North American transportation requirements. Its single engine platform is HVO fuel ready and EPA On-Highway and CARB On-Road compliant.

“This crane represents Link-Belt’s long-term AT investment, which goes back to 2009 with construction of our own formed boom bay and subsequent ATC-3275 introduction,” said Soper.

Lifting

The 300|AT is well equipped with a seven section 46 - 238 ft. (13 – 72.5 m) pin and latch greaseless formed boom and optional two-piece 42-71 ft. (12.8 – 21.6 m) on-board hydraulically offset fly and two 25 ft. (7.6 m) lattice extensions. Maximum attachment will achieve a tip height of 369 ft. (112 m) and an efficient modular counterweight configuration adds to the 300|AT’s versatility. Maximum counterweight is 162,000 lbs. (73 481 kg) with four overflow truckloads, and for

improved mobility and efficiency for a variety of jobsite scenarios the 300|AT can be set up with two overflow loads and 74,000 lbs. (33 565 kg) of counterweight. Another improvement to the 300|AT’s mobility is the option of transporting the 300|AT with its upper 8,000 lbs. (3 628 kg) counterweight tray and still stay below 160,000 lbs. (72 574 kg) gross vehicle weight [23,000 lbs. (10 432 kg) per axle].

The 8 ft. (2.4 m) heavy lift fly provides robust capacities and line separation for two load line operation in applications like precast wall panels. Time tested and proven features such as greaseless sheaves and Teflon wear pads cut maintenance and service costs. Additional standard boom features include wireless wind speed indicator, single-hand operation rope guard, and three work lights on the boom base section.

The 300|AT will also feature

SmartFly. Link-Belt’s simple, intuitive SmartFly system ensures proper fly erection and stowage sequence while minimizing work at height.

Link-Belt fly erection procedures have been embraced in the market on most all of Link-Belt’s telescopic product line for their ease of assembly and one person operation.

Features

A single 554 hp (407 kW) Cummins X15 diesel engine with ZF Traxon automated manual transmission delivers best-in-class power on the 300|AT.

The transmission features improved shifting performance and offers integrated intarder braking with paddle shift controls for easy stopand-go at highway speeds.

The 300|AT also features an innovative new power transmission system for efficiently powering upper hydraulic functions. It offers a 24 volt electrical system with an optimized, modern CANBUS communications.Customers will

recognize the purpose-built twoperson carrier cab from the 175|AT on the new 300|AT.

The interior features amenities such as automatic climate control, blue tooth radio, cell phone charging and LED lighting. An air ride seat with lumbar support provides optimum comfort while driving.

Operator’s Cab

The operator’s cab is a legacy success story, tailored for all-terrain operations. Pulse 2.0 with its 10 in. (25.4 cm) touch display is at the heart of this crane with features and controls that are intuitive, adaptable, and in easy arm’s reach.

The view from the seat is unimpeded in any kind of weather with large sweeping wipers in the front and top, and strategicallyplaced vents for quick defrost.

Another new feature to Link-Belt’s all-terrain lineup is the improved flexibility of V-CALC, an infinitely variable outrigger positioning that allows for setup in tight jobsite conditions where outriggers require being unevenly extended (0%, 40%,

70%, 100% extension). All capacities are printed in crane rating manual and automatic swing function kickout works to maintain forward and backward stability.

Standard carrier features that operators are accustomed to include: four points of access to the flat carrier deck, a comprehensive camera “Site Vision” package, and the premiere lighting package on the market for nighttime operations.

Other standout features of the 300|AT include:

• Wireless rigging remote (carrier function, upper function, fly erection)

• Tire pressure and temperature monitoring system

• SmartStack counterweight detection system

• Tie offs at all dedicated anchor points for multiple work positions

• Flat carrier deck

Grove launches the new GRT8100-1 rough-terrain crane

This exciting upgrade of the hugely popular GRT8100 will be available from 2023 and offers a series of improvements over the original GRT8100. Many of the enhancements stem from a new chassis that shares commonality with the chassis from the proven 120 t capacity GRT8120. There’s also an updated engine and transmission package, and a new,

wider cab with enhanced operating features. “The GRT8100 has been a popular choice with customers worldwide. With the GRT81001, we have taken a great crane and made it even better,” said Federico Lovera, product manager for rough-terrain, industrial, and lattice boom crawler cranes at Manitowoc. “The new Grove GRT8100-1 will go into production

at our U.S. and Italian factories simultaneously, allowing deliveries to customers around the world to begin in early Q2 next year.” The 100 t (100 USt) capacity GRT8100-1 features the same impressive 360° load charts as its predecessor. It also maintains the same overall dimensions, counterweight, and five-section, 12 - 47 m (39.2 - 154.3 ft) full-power MEGAFORM® boom. However, with the new chassis on the GRT8100-1 customers have the option to integrate the highly flexible MAXbase variable position outrigger system, which offers up to 15% capacity improvements in certain configurations. MAXbase also greatly simplifies setup on congested jobsites, with each of the four hydraulically telescoping outriggers extended over a range of symmetric and asymmetric positions.

Also new to the outrigger design is an auto-level feature for easy jobsite set-up, as well as Manitowoc’s smart, length-sensing Outrigger Monitoring System (OMS).

The

upgraded version of the popular GRT8100 rough-terrain crane benefits from a new carrier that features MAXbase, the variable outrigger positioning system that enables better lifting capacity and site access.

Access all areas

The new carrier paves the way for a host of ergonomic improvements, with its flat, aluminum decking allowing for better rigging and maintenance access. Storage is improved, with the addition of space around the front deck plus a box and headache ball tray to the right-front side.

On the left side, below the new cab, there is space to stow cribbing mats, while a compartment just above this includes not only additional storage, but also facilitates easy ground access to carrier electrical components.

Operator comfort is improved thanks to a new, wider Full Vision cab with features such as a tilt/telescopic steering column, a wider, heated, electrically adjustable seat, and a three-camera package that maximizes visibility around the crane.

The larger door and wrap-around hand railing and grab bars encourage more secure access.

A new LED lighting package includes new installations on each side of the carrier plus dual, front-mounted lights on the 20° tiltable cab for a clearer view of the load and fewer blind spots.

A host of new standard features include footrest bars, improved foot pedal spacing, all-weather, molded floor mat, fold-down shelves behind the seat, a pivoting cup holder, USB charging port, a windshield sun visor, and a windshield washer for the skylight.

Manitowoc’s Crane Control System (CCS) is now mounted on adjustable arms for easy adaptation with convenient and comfortable control coming from the armrest jog dial.

Also included within CCS is the on-Crane Service Interface (0CSI) which provides enhanced diagnostics and monitoring systems for easy maintenance.

Fuel’s gold

CCS also helps deliver significant savings in total cost of ownership on the GRT8100-1, allowing the new 6-cylinder, turbocharged and water-cooled Cummins B6.7L engine to operate in ECO mode.

Here, the reduced engine speeds that promote improvements in fuel efficiency have been aided by the torque convertor installed with the new Rangeshift transmission.

Repowered to ensure compliance with Euromot Stage 5/Tier 4 Final regulations, the new crane benefits from approximately 10% more power, producing 224 kW (300 HP) at 2,500 rpm, while its single-module aftertreatment system with DEF reduces complexity and saves weight.

Overview of the hydrogen strategy

Manitou Group, a world reference in the handling, aerial work platform and earth moving sectors, presents its roadmap for research and development on hydrogen-powered machines. Its opportunity to present the first innovative prototype telehandler running on green hydrogen.

Energy transition acceleration

With a target of reducing greenhouse gas emissions by 34% per hour of use of its machines in 2030, Manitou Group has set off on an ambitious course, in line with the commitments of its low-carbon trajectory communicated in January 2022 and validated by the SBTi in July.

Following on from the recent electrification of its all-terrain platform and telehandler ranges, the Group is also looking to hydrogen as a medium-term alternative for its users.

Manitou Group wants to see its electric and hydrogen ranges side by side depending on each user’s applications, with a target of 43%

low-emissions products marketed in 2030.

A dedicated hydrogen development plan

Manitou Group has presented its new facilities for making its hydrogen development plan a success to journalists and elected representatives. By kitting its test center out with a green hydrogen station, the Group now has the means for testing its brand new prototype telehandler.

The first step of this plan involves guaranteeing range and reliability in real-life conditions, while testing the durability of components.

The Group based this first prototype on an existing model from its range of construction machines, capable of lifting loads up to 14 m.

This machine will be tested and sent out to construction sites by the end of 2023 with a view to collecting valuable feedback from

users to improve on this prototype. Two types of hydrogen technology are currently being evaluated by the market, namely the combustion engine and the fuel cell.

The Group’s first prototype is built around a fuel cell, but the Group will choose the hydrogen solutions that best meet the needs of its customers. Michel Denis, Managing Director of the Group, explains: “We are studying all the hydrogenrelated technologies based on what users need. This prototype is only the first step. A second rotating telehandler prototype will be developed in the coming months. There are many benefits of green hydrogen with production possible using wind power that has no greenhouse gas emissions at all. This fits in perfectly with our lowcarbon trajectory”.

With this first prototype, the Group is showcasing its ability to innovate in order to measure the autonomy of this new energy while offering its customers the hydrogen solution that best meets their needs, but without compromising on performance. Almost 50

dedicated to this approach, which was launched in 2021. To come up with an innovative solution that can be fully industrialized, the Group hopes to rely on the support of the public authorities to develop an emerging ecosystem. Julien Waechter, VP R&D Manitou Group, explains: “The green hydrogen sector is gradually becoming more established with the entry onto this market of a number of players. All of the aid mechanisms proposed by the different governments will encourage the transition to hydrogen, and will speed up the development of the distribution network and ultimately the reduction in the usage costs of our machines using this energy”.

With these new facilities, Manitou Group hopes to offer its customers new innovative prospects, with a 100% hydrogen-powered telehandler available on the market by 2026.

Innovation in our DNA

With over 350 engineers on its workforce, Manitou Group is constantly innovating by offering its users highadded-value solutions. To

€60 million a year in all of its 10 R&D centers around the world. The modernization of its production units is also essential to ensure this ability to innovate.

This is demonstrated by the recent €150 million investment plan announced for the production sites in the US and France. The most recent aerial work platform factory opened in 2022 clearly illustrates this willingness.

Whether it concerns the choice of components, user comfort, or the attachment on the machine, innovation is everywhere.

An autonomous order-picking robot, electric all-terrain platforms, and 100% electric telehandlers are all examples of innovation.

To support this development, the Group incorporates engaging CSR criteria from the design stage to develop machines that are increasingly durable and responsible.

How to choose the correct clamp for your lifting application

Do you need a new below-the-hook lifting device and think a clamp could be the right fit? When it comes to lifting clamps, there are plenty of options. However, when choosing a clamp, how do you know you’re picking the correct one for your lifting applications?

To answer this question properly, we reached out to engineering manager Dale Kelly of Caldwell / J.C. Renfroe Lifting Solutions in Rockford, Illinois to help outline what you need to know before choosing a clamp.

Factors you need to consider when choosing a clamp for your overhead lifts, including:

• Hardness of the metal

• How you plan on lifting with a clamp

• What kind of jaw opening is needed for your application

• The environment will the clamp be used

• Confirmation upon receipt of the clamp

Lifting is “MAJEC”

Really, there is no “magic” involved in overhead lifting and material

handling, at least there shouldn’t be. It is part art, part science in which all details must be considered beforehand to help ensure safe lifts. However, the acronym “MAJEC” will help you choose the correct clamp needed to safely make your overhead lifts.

The acronym, “MAJEC” stands for:

• Material Hardness

• Attitude of the lift

• Jaw opening

• Environment

• Confirmation through reading the manual, inspections and size (witness marks)

By going over the topics in the acronym, you can learn most of everything you need to know about how to choose the appropriate clamp for your application. Knowing this acronym will help develop a greater understanding of your:

• Materials

• Lifts

• Clamps

• Surroundings

• Processes

Breaking Down the Components of “MAJEC” Metal Hardness

If the hardness of the metal is above 300 Brinell, which is measured on a machine or the certification that comes with the metal, the teeth of a clamp can’t penetrate into the steel. That will prevent the clamp from being able to do its job.

Caldwell / J.C. Renfroe has special clamps designed for plates above 300 Brinell, and those clamps are part of the non-marring series.

They have a smooth jaw and a higher grip ratio that can grip the plate without slipping. Non-marring clamps have smooth jaws, and they will not leave marks on your plates. Therefore, it can be used on softer materials as well. This is especially true for plates that are sensitive to teeth marks where you need a polished surface. If the plate metal is below 300 Brinell, clamps with teeth on them can be used for lifting. These teeth must remain sharp, and the properly sized clamp will grip the plate, penetrate the steel, and allow it to lift and do the job that needs to be done.

Attitude of the Lift

What “attitude” refers to is how you want to lift your plates. The following questions must be asked and answered to ensure you have the proper clamp for your lifts:

• Are you lifting plates vertically?

• Do you want to turn the plate during the lift?

• Do you need to flip the plates over during the lift?

• Is there another type of orientation that you must have to lift a plate?

If you want to lift a plate vertically, Caldwell / J.C. Renfroe’s FR clamp is a good choice. It’s a vertical-only lifting clamp meant to lift a plate on edge, straight up and down.

The next style of clamp is called the vertical plus 90. The Caldwell / J.C. Renfroe Model TL Clamp is rated to turn a plate from flat to 90° and back through the same angle. It has a locking lever on it that maintains constant pressure on the plate so the teeth can always penetrate during no-load conditions. Such conditions include when a plate is standing straight up and resting on the ground.

Also, Caldwell / J.C. Renfroe offers you clamps that can flip plates over completely. They have the following components that allow them to function properly:

• A pivoting jaw

• Lock

• Additional lock Clamps

for Special Lifting Conditions

The additional lock is a good safety feature, as when you’re flipping a plate completely over, if you happen to hit an obstruction, the clamp won’t unlock and disengage from the plate. The Caldwell / J.C. Renfroe JPA Model comes with a pivoting shackle that allows it to be used in pairs with a central lift point.

For plates that are lifted in a flat manner, meaning they are hoisted straight up and straight down, horizontal clamps should be used. You use these in pairs, and they are for lifting plates in a flat manner, straight up and straight down, and for transport through the shops. It does not turn, and there’s no side-loading allowed.

Caldwell / J.C. Renfroe has an SCPA model, and this clamp is rated to turn 180°. It has a pivoting shackle, so you can use it in pairs with a central hoist and a spreader beam when lifting a plate that’s standing vertically. As an added bonus, the robustness of this clamp is good for high vibration environments, and that’s where Caldwell / J.C. Renfroe clamps start to break down and become more specialized throughout the product line.

Fast assembly instead of festooning

The cable carrier guidelok swing GLO.S increases the safety in the operation of swing cranes. The cost-effective alternative to cable loops reliably protects the cables and thus prevents them from getting tangled and tearing off. The space-saving system thus ensures increased system availability and reduces downtime costs.

Jaw Opening

All Caldwell / J.C. Renfroe clamps are identified and have the jaw opening on the label. It is important that you always follow the restrictions listed on the clamp’s tags.

Remember, just because a plate fits in the jaws doesn’t necessarily mean it’s the appropriate clamp for a plate’s thickness. The reason is because once the clamp’s teeth penetrate, they can upset the metal, and now, the plate gets thicker and your plate can get stuck in the jaw. This will prevent the clamp from releasing. Again, always follow the recommended jaw range that’s listed on the tag for each individual clamp.

Environmental Considerations

The next important item you need to consider is the environment you intend on using the clamp in. You need to identify if the clamps will be used in chemical conditions, sand conditions, and what kinds of temperatures (either extreme heat or cold), as all of those factors can affect the usability of the clamp.

All the Caldwell / J.C. Renfroe standard clamps have a temperature range of 0° to 93°. If the temperature range is beyond 0° to 93°, and it becomes too cold, the metal in the clamp can become brittle and cause the clamp to fail. When the temperature is too hot, it can damage the teeth and cause them to melt or lose their hardness and cause it to fail.

If your working conditions are

outside of the 0° to 93°range, call your sales representative and tell them your desires to use a clamp in an environment that’s outside that range. Let the representative choose the appropriate clamp for the job. Caldwell / J.C. Renfroe does offer hot lift clamps that are capable of being used in environments up to 540°F. Certain clamps shouldn’t be used in sand-blasting environments, and that includes screw clamps. The sand could get stuck and affect the threads. Acids and alkalines can attack the teeth and cause them to dull out. For these environments, Caldwell / J.C. Renfroe offers special materials that can withstand the caustic environments created by acids and give your clamps better lifespans for that work.

Confirmation

To confirm that you chose the right clamp, first you’ll want to read the clamp’s accompanying manual. Then, you’ll want to inspect your clamp to make sure everything is in operable condition, and that includes having a legible tag. During the inspection, you’re looking to make sure the teeth are sharp, and the bolts holding the clamp together are tight.

Then, you will use your new clamp to conduct a test lift and check your “witness marks.” The first step in this process is outfitting yourself with the required PPE (personal protective equipment), which could include:

• Safety glasses

• Steel-toe boots

• Hard hat (where applicable)

• Anything else your company requires you to wear for safety purposes

“Witness marks” are the marks left on the plates after a load has been applied to your clamp. During a test lift, you want take your clamp, apply it to your plate, tilting it at approximately a 20-30° angle and lock the lock handle. Then, you’ll tilt the clamp back up, leaving a 1/4” gap between the edge of the plate and the interior side of the jaw.

This allows the clamp to seat properly. Then, you’ll hook up the clamp to a hoist, and apply just enough load to lift the plate off the floor before returning the load to the ground.

Once the plate is back on the ground, you’ll want to remove the clamp from the hoist, and disconnect it from the plate so you can inspect the witness marks. If you can feel an indentation, that clamp is suitable for your application.

When Would Clamps Not Be the Right Fit?

Sometimes, a clamp is not the right fit for your lifting application. In fact, if used improperly, clamps can be a hazard instead of a help. This is especially true for the following plates:

• Diamond plate

• Coated plate

Caldwell / J.C. Renfroe recommends using clamps ONLY on plates that are clean and have no coatings so the clamp can get a proper engagement.

Where Can You Use Clamps for Overhead Lifts?

A good application for any Caldwell / J.C. Renfroe clamp is a clean metal plate of proper hardness that’s a flat surface.

Many of these clamps are used in shipyards for boat building. This is a good fit because the clamps help:

• Save time

• Increase efficiency

• Provide a safer work environment

How do I select and install trolleys for manual and powered hoists?

Trolleys are available for underhung lug-mounted hoists and underhung hook-mounted hoists for monorails and single girder cranes.

Types of Trolleys

Trolleys for Lug-Mounted Hoists

A lug-mounted hoist requires mechanical fasteners, including varying types of hardware and pins, to attach it to the trolley. The hoist gets attached directly to the trolley rigidly. That eliminates any flexing between the trolley and the hoist.

Underhung trolleys for monorails and single girder cranes for lugmounted hoists include:

• Push / Pull Trolley

• Motor-Driven Trolley

• Hand-Geared Trolley

Trolleys for Hook-Mounted Hoists

A hook-mounted hoist is one that uses a hook suspension to join the hoist to the trolley. These hoists are two individual components. The trolley is one individual unit, and it will have an eye at the bottom of it to which you can attach a hook.

Underhung trolleys for monorails and single girder cranes for hookmounted hoists include:

• Push / Pull Trolley

• Motorized Trolley

• Motorized Tractor Drive Trolley

• Hand-Geared Trolley

Tractor Drive Trolleys pull themselves along the bottom of the beam hanging from the wheels on the flange.

What To Know about Beams?

Trolleys are designed to fit specific beam flange sizes. Thus, you may not easily be able to convert trolleys from one flange size to another. While there could be two trolleys that fit the same beam, one trolley might be at its maximum adjustability range and the other might be at its minimum adjustability range.

Sometimes, price dictates the

type of trolley you’ll purchase, but also, it could come down to availability or capacity. Switching a trolley from one flange to another requires removing certain pieces of hardware and adjusting the trolley side plates.

Standard Beams

There are many types of beams in use on the market, and they include:

“S” Section Beams, also known as “I” Beams

“W” Section Beams, which are also referred to as “H” or “WF” (Wide Flange) Beams

The “S” and “I” beams have a flange slope of 9°, while “W,” “H,” and “WF” beams have a flange slope of 0° to 2°. In some cases, these different beams can accept a universal wheel fit, but there are times when a universal wheel

will not work properly. That would depend on the capacity and the size of the trolley.

Patented Track Beams

Patented Track Beams are manufactured tracks.

The inside track where the wheel of the trolley would ride typically is harder than the traveling surface of an “S” beam or the “WF” beams. That gives more longevity to the trolley wheel and will not be as susceptible to wear. That will save you downtime and money because the trolley will not need to be repaired or replaced as often as it would while installing and running on an “S” or “WF” beam.

While that is a big strength, there are some disadvantages to using a patented track beam. The wheels on the track are harder to match the hardness of the track. Those wheels tend to be narrower, so there is less contact between the beam and the wheel. You won’t have as much friction to stop, so the trolley’s braking system needs to be up to date and stronger than a normal system. Patented Track Beams are used a lot in curved sections because it tends to be stronger and have better longevity than a standard “WF” or “S” beam. These beams can be shaped and formed in different ways.

Selecting the Correct Trolley

In order to choose the right trolley for your beam, you either have to know or have an evaluation done to gather the following information about your working environment:

• Beam Shape

• “S” or “W” Section

• Patented Track

• Fabricated

• Beam Depth / Height

• Flange Width

• Flange Thickness

• Curve Radius and Type

• Measures radius

• 90°, 180°, or “S” curve

Disassembly and Reassembly of Trolleys

When any kind of maintenance is done, trolley wheels must be checked because they’re subject to the most wear. Just like the tires on a car, when in use, trolley

wheels are the first component that will experience wear. The wheel bearings will need to be lubricated periodically. For more regular use, the bearings will need to be lubricated more often. Conversely, less frequently used trolleys will not need to have their bearings lubricated as often. Wheels should be lubricated with a manufacturer-supplied or recommended grease or oil.

Trolley Wheels

Trolley wheels are made from medium carbon-forged steel or cast iron. They have a dual-tapered tread to run on both “S” and “W” Section beams, and are equipped with precision ball bearings.

Patented Track Wheels

Patented track wheels have a narrow flat tread, and are heattreated to 425 BHM to meet patented track requirements.

Trolley

Construction

With many motor-driven trolley models, they will include VFDs (Variable Frequency Drives). Many manufacturers offer these units on their trolleys. The VFDs help ramp up or ramp down a trolley gradually, which will reduce high-impact collisions against the ends of the beams. The speeds can be adjusted based on your specific needs.

If you’re moving a hot material or a liquid (i.e. acids, plating compound), you don’t want it to spill. This is

where the slow ramp up and ramp down comes into play. It helps you avoid a potential incident.

Key things to understand with trolley construction include:

• Structural steel side plates

• Drop stops bolt-on option on Shaw-Box models

• Rubber bumpers are optional

• The side plates are load-bearing, so they need to be inspected periodically

• Right angle worm gear reducers

• Provides braking to stop unit within 10% of rated speed

• Squirrel cage induction motors

• Similar features as hoist motor, except NEMA Design B motors

• VFD duty standard

• Controls

• Single-speed contactor standard

• Two-speed contactor and VFD available options

With trolleys, the following must be inspected periodically:

• Trolley wheels (plain or geared)

• Drop stops

• Space washers with nuts

• Warning label

• Suspension bolt nuts

• Load bracket

• Side plates (plain or geared)

• Suspension plate

When trolleys are purchased, the manufacturer will put in enough spacers and washers in the unit so you can configure that trolley from the minimum flange thickness allowed to the maximum.

HOISTS

You cannot add additional non-OEM (Original Equipment Manufacturer)supplied spacers or washers to the trolley to fit on a bigger beam. Instead, you need to purchase a different trolley.

The suspension bolts are designed only to go to the maximum flange thickness that the trolley is made for.

How Do I Properly Fit a Trolley to a Beam?

Once it is determined that the trolley is compatible with the beam, the next step is to adjust the width of a trolley to fit the beam.

In order to adjust the width of the trolley, you want to:

• Remove one set of locking nuts on one side of the trolley

• Remove the washers / spacers from the shaft

• Space the trolley wheels the appropriate distance to fit the

designated flange using the washers / spacers

• Set the distance on one side of the trolley and leave the other side loose

The next step includes:

• Placing the trolley on the selected flange with assistance from a person, jack, tow motor, or another hoist

• You may be attaching a lugmounted trolley separately or with the hoist affixed to the trolley, so this assembly can be heavy SO USE CAUTION.

• Assembling the last side plate to the trolley with the appropriate washers / spacers and tighten the remaining locking nuts

• Checking the clearance between the flange of the trolley wheel and the edge of the flange of the beam

• The gap should measure 1/8” to 3/16” greater than the flange width or what the manufacturer

recommends

• Ensuring the trolley moves along the beam freely, and make adjustments as needed

• If the trolley is powered, test that the controls match the movements of the trolley, as well as the hoist

In working to select and install a new trolley for your manual or powered hoists, you must understand:

• The different types of trolleys and beams

• How to select and install trolleys for hoists

• Proper procedures for trolley use and inspection

• Operation of the trolley and its brakes

• Disassembly and reassembly of trolleys

• Performing a routine inspection

• Troubleshooting trolley issues

• Properly fitting a trolley to a beam www.mazzellacompanies.com

CHAINS

Energy chains vs. motor cable drums

The advantages and disadvantages of two industrial energy supply systems. Whenever design engineers have to guide hoses and power and data cables in moving applications with long travels (more than 100 metres), the question arises of which energy supply system is the most efficient.

Whenever design engineers have to guide hoses and power and data cables in moving applications with long travels (more than 100 metres), the question arises of which energy supply system is the most efficient, especially considering such factors as reliability, maintainability, and future security?

A motor cable drum? Or an energy chain? The advantages and disadvantages of the two systems are explored below.

The motor cable drum

A proven energy supply that has been in use for decades – in applications such as cranes, transfer carriages, and the bulk material industry. The principle is simple. It is in its simplest form like a garden hose reel. When a gantry crane, for example, moves back and forth on its four supports, the cable is deposited on a prepared surface on the ground and is rolled back up on a drum mounted on one of the supports. There are several variants for retracting the cable. In addition to motorised drums, there are

designs for shorter travels that work with spring force: the rolling action is normally either cylindrical or spiral rolling. In the cylindrical form, also called broad rolling, the cable first rolls up from left to right along the drum body.

Then it rolls up vertically, layer by layer. Spiral rolling works differently. The cable is stacked immediately after the first rotation. The market for cable drums is growing. A key region is North America, and one reason is because the demand for cranes in the northern United States is rising. Another booming region is the Asia-Pacific, especially China and Japan. Among the reasons for this is urbanisation and a flourishing construction industry. According to Persistence Market Research, a market research institute, the global market volume will be more than $3.4 billion in 2026.

The energy chain

An alternative for guiding cables on cranes, handling portals, or stackers/reclaimers is the socalled energy chain. This option

is a mobile protective cage. It consists of parallel side links that are connected with crossbars along the top and bottom of the carrier. When the system moves, the chain folds, and the upper run glides on the lower run. No motor is required; the chain is attached to the crane's boom, for example, and moves with the movement of the crane.

Like the cable reel, the energy chain has been well-tried. Inventor Gilbert Waninger launched the chain in 1953. At the time, it was entirely made of steel, but today's manufacturers are more flexible. Since 1969, companies have developed high-performance plastics that can be used under a wide variety of environmental conditions – constant contact with salt water and heat in metal works, for example.

Energy chain vs. motor cable drum

Installation space and weight

Energy chains generally have weight advantages for long travels. If the chain folds, the upper and lower run reach a height of around 800

mm, depending on filling and chain series. This makes them compact. Motorised cable drums operate differently. They do not require guide troughs, saving space on the user’s travel path. But in many applications, their drums have diameters of 6,000 mm or more. If this space is not available, the cable drum cannot be used as a solution. Another disadvantage of drums is that they are relatively heavy. This makes systems heavier and lowers their energy efficiency. The crane's structure must also be designed for this additional load. Sample calculation: for a travel of 400 metres in length and a cable weight of 10 kg/m, the additional weight of the rolled-up cable is about 4 t. Then there is the weight of the drum, the steel structure, and the drive technology. Energy chains made of high-performance polymers, on the other hand, are much lighter and contribute to energy savings. No additional load must be calculated on the crane.

Assembly

Motor cable drums may have an advantage in this round, since their functionality is very simple. It is just as easy and fast to assemble the drums. Energy chains are also relatively quick to assemble, especially when users order the system with cables and plug-in connectors so that it is ready to connect. However, only qualified technicians should carry out the assembly. For long travels, a guide trough is obligatory for gliding applications (when the upper run lies on the lower run), and an energy chain riser guard or an enclosure that protects the system from weather may be recommended as necessary. This allows safe operation under any weather conditions.

Cable protection

The task of motor cable drums and energy chains is to protect moving cables and hoses from mechanical loads. The chain comes out ahead here, since it guides cables and hoses safely through the interior separation and relieves strain at the fixed and moving ends. They are subjected to neither tensile forces nor high mechanical loads

during movement. Moreover, some high-performance polymers have vibration-damping properties. The cables and hoses are protected from wear along their entire length. Motorised cable drums operate differently. There is a constant tensile force during rolling and unrolling so that the cable experiences a greater load, reducing its service life.

Wear and maintenance

Motor cable drum manufacturers now have corrosion largely under control. But in extreme environments, such as offshore facilities, rust can force operators to intensively maintain or replace their motorised drums over the course of the years. Bearings and the slip ring body are the elements that are especially affected by corrosion and wear.

At worst, this can cause long, expensive system downtime. Then there is occasional maintenance work for guide elements, clamp connections, and motor and switch deflectors. This means that operating motor cable drums involves time and expenditure. Energy chains operate differently. High-performance polymer variants are resistant to chemicals, saltwater, and UV radiation. The result is that, in some applications, energy chains can be operated for almost ten years with hardly any maintenance.

Combinability and extendability

Transmitting energy and data via motor cable drums requires either different drums or expensive special cables. If additional fibre optic cables or hoses for supplying air, water, or oil must be moved, additional drums and components are indispensable.

Energy chains, on the other hand, accommodate the use of a wide variety of cables and hoses in a single system from the very beginning. In order to react flexibly to technological trends, they allow easy addition of other cables if reserve space is set aside from the beginning of operation. This is not true of motor cable drums: it is very difficult to add hoses or cables later on. To do so, the operator needs

either a special design or additional drums.

Compatibility with Industry 4.0

In the Industry 4.0 era, more and more users are integrating machines and systems into the Internet of Things in order to digitise processes.

This enables systems to autonomously call attention to a problem. Energy chains come out ahead here. Manufacturers have begun equipping energy chains with break detection systems and push/pull force systems. Anomalies in set parameters, such as those caused by breakage in a chain link or blockage in the energy chain run, can activate emergency stop systems or trigger maintenance missions in good time. Before there is expensive system failure.

Operation and speed

Today, industry everywhere requires faster turnaround times, which necessitates faster and faster travel speeds for moving equipment. A system with motor cable drums can achieve average travel speeds of up to 120 m/min (up to 300 m/min with limitations). An energy chain system with integrated rollers in the chain link can reach travel speeds of 600 m/min.

And that speed is constant across the entire distance. Systems with motor cable drums must brake when they reach or pass infeed points so that the cable can be properly rolled up or deflected.

Conclusion

Energy chain or motor cable drum: which energy supply system comes out ahead? There is no blanket answer because, in the industrial world, no two applications have exactly the same conditions. Different elements are weighted differently. Some points favour the motor cable drum – among these are its simple assembly. Others, such as cable protection, largely maintenance-free operation, and the extendibility, favour the energy chain.
